SASH HOLDER.

Application led December 7, 1927. Serial No. 238,392. l

This invention relates to window sash holders and particularly to thoseused in connection with window sash which do not have window weights. ln

In many types of houses and other b uildings it has become the practiceto provldea window sash with means for holding it in any desiredposition without the use of counterbalance weights. This practice wasprevalent many years ago and is well known and understood, and is stilloccasionally necessary on account of the cost of building. Many of thedevices used heretofore have been extremely ineective in holding thesash in any desired position and yet permitting it to be moved freely toclosed position.

The object of the present invention therefore is to provide a holdingdevice for a window sash which shall be simple in construction andcertain in operation.

The exact nature of the invention will be apparent from the followingdescription taken in connection with the accompanying drawings in whichFig. 1 is a sectional elevation of pertinent parts of a windowinstallation to which my device has been applied showing the device inelevation with portions cut away to show construction; Fig. 2 is a viewof the device itself, looking from a different direction as from theright side of the device when positioned as in Fig. 1.

The principal member of the device is a base or frame 1 having a pair ofside portions 2, a through opening 3 therebetween, and end portions 4drilled as indicated to receive screws by which the base may be securedwhen set into the recess 5 of the side members 6 of a window sash ofwhich 7 represents the pane of glass.

Extending between the side portions 2 of the base is a pin 8 upon whichis mounted between the side portions a lever 9. The lever has a long endupon which is formed a projection 10 opposite a similar projection 11 onthe base; the projection serving to position a helical compressionspring 12 whereby the lever 9 is yieldably urged in clockwise directionFig. 1. The opposite end of the lever carries a pin 13 of suilicientlength to overhang the side portions 2 of the base and thus limit springurged movement of the lever 9 by bearing against the shoulder portions14 of the base side portions. Upon the pin 13 is mounted a generallyU-shaped rocker 15 having two side members carrying between them the pin16 and a connecting web portion 17. AAfroller 18 is mounted upon the pin16. Motion of the rocker 15 upon the pin- 13 is limited in clockwisedirection Fig. 1, by engagement of the roller with the lever 9 asindicated, and in counter-clockwise direction, Fig. 1, by engagement bythe web 17 withI the lever.

lVhen the parts are assembled as described the spring 12 will cause theroller 18 to be urged outwardly of the face 19 of the base and sash.This outward movement however, being limited by the pin 13 abutting theshoulders 14 of the base.

Operation will be as follows assuming the window sash to which thedevice has been applied has been mounted in a window frame of which themember 2O lies adjacent the member 6. The clearance between the members6 and 20 of the sash and framerespectively is such that the roller whichis preferably of non-metallic material such as fabric, will at all timesbe caused to bear against the member 20 by the spring 12. Assuming thewindow half way open, that is the sash slid half way up, the parts arein the position shown. At this time the tendency of the sash is to slidedownwards due to gravity but the bearing of the roller against the frameserves to move the rocker counter clockwise about its pivot so that theroller bears also against the lever which has suiiicient braking actionupon the roller to prevent rotation thereof. The spring 12 is ofsuiiicient strength and the friction of the roller material is such thatthe window is maintained in this position.

Should it be desired to raise the window further upward movement of thesash eifects counter clockwise (Fig. 1) movement of the rocker :freeingthe roller from the lever and therefore freeing the sash in the frame.To close, the sash is lowered, the roller sliding upon the frame member2O with justv suiiicient friction to odset the :torce of gravity.

It will be noted that the roller is positively positioned through themounting of its axis pin 16 in the rocker so that the tendency to jamdue to misalignment of the roller is positively prevented. It will alsobe noted that the tilting motion of the rocker is limited by the meansdescribed to a small angle in which the arc travelled by the axis pinextends only slightly above and below the elevation, Fig. 1, of the pin13; so that motion of the roller is substantially independent oi theangular position of the rocker, and therefore govern-ed practicallysolely by the bearing of the roller against the iframe member 20.

IWhat I claim is:

l. In an article of the class described, a base adapted to be tted to aWindow sash and having side portions, a lever movable on said base. arocker, a pin connecting said lever and rocker whereby the latter isCarried by the former, a roller mounted on said rocker, spring meansarranged to yieldably urge said lever to maintain said roller bearingagainst the frame in which said sash slides, said pin overlying saidbase side portions and being adapted to engage the same to limit movement of said lever, sai-d rocker being arranged to move said roller tobear against said lever or to free the saine therefrom dependent uponrelative movement of said sash and frame.

2. In an article of the class described, a base adapted to be fitted toa Window sash, a lever movable on said base, a rocker carried by saidlever, a roller mounted on said rocker, spring;v means arranged toyieldably urge said lever to maintain said roller bearing against theiframe in which said sash slides, said rocker being arranged to movesaid roller to bear against said lever or to free the same therefrom,dependent upon relative movement of said sash and frame, and having aweb portion adapted to abut said lever to limit said roller reeinzg`movement.

In testimony whereof I hereby aiix my signature.
